   <p>
    <!-- Emits a single logical value onto a wire. For the power element,(<img class="intxt" src="../../../../icons/1616/power.png" alt="#########">) indicated by a triangle , this value will be <b class="unov">1</b> (or, if the Data Bits attribute is greater than 1, an all-1's value). For a ground element,(<img class="intxt" src="../../../../icons/1616/ground.png" alt="#########">) indicated by an arrow of three decreasing-length, horizontal lines, this value will be <b class="zerov">0</b> (or, if the Data Bits attribute is more than 1, an all-0's value). -->
    将单个逻辑值发送到线路上。 对于 power 元素，(
    <img alt="#########" class="intxt" src="../../../../icons/1616/power.png"/>
    ）由三角形 表示，该值将为
    <b class="unov">
     1
    </b>
    （或者，如果数据位属性大于 1，则为全 1 的值）。 对于地面元素，(
    <img alt="#########" class="intxt" src="../../../../icons/1616/ground.png"/>
    ）由三个长度递减的水平线箭头指示，该值将为
    <b class="zerov">
     0
    </b>
    （或者，如果数据位属性大于 1，则为全 0 的值） 。
   </p>
   <p>
    <!-- The same functionality can be achieved by using the more versatile <a href="constant.html">Constant</a> component. The only reason to prefer ground and power is that they are commonly-used electronic symbols. -->
    使用更通用的
    <a href="constant.html">
     Constant
    </a>
    组件可以实现相同的功能。 更喜欢接地和电源的唯一原因是它们是常用的电子符号。

   <h2>
    <!-- Pins -->
    引脚
   </h2>
   <p>
    <!-- Each component has only one pin, an output whose bit-width matches the Data Bits attribute. The component constantly outputs the same value on this pin: for a ground component, the output is an all-0 value, and for a power component, the output is an all-1 value. -->
    每个元件只有一个引脚，即位宽与数据位属性匹配的输出。 该元件在此引脚上不断输出相同的值：对于接地元件，输出为全 0 值，对于功率组件，输出为全 1 值。

   <p>
    <!-- When the component is selected or being added, <b class="tkeybd">Alt-0</b> through <b class="tkeybd">Alt-9</b> alter its <b class="propertie">Data Bits</b> attribute. Quick use of the keys allows the entry of larger values for example <b class="tkeybd">Alt-0</b>ALT-1 ALT-2</b> gives 12. The arrow keys alter its <b class="propertie">Facing</b> attribute. -->
    选择或添加元件时，
    <b class="tkeybd">
     Alt-0
    </b>
    到

     Alt-9
    </b>
    会更改其
    <b class="propertie">
     数据位
    </b>
    属性。 快速使用按键可以输入更大的值，例如
    <b class="tkeybd">
     Alt-0
    </b>
    ALT-1 ALT-2
    给出12。箭头键改变其
    <b class='“propertie"'>
